Heat waves are hitting Antarctica too now
The world saw another year full of extreme weather events resulting from climate change in 2022, from intense storms to soaring temperatures and rising sea levels. Antarctica was no exception, according to new research published this week......»»
Improved method for phonon lasers "locks" sound waves into a more stable and powerful state
Scientists have made a significant leap in developing lasers that use sound waves instead of light. These phonon lasers hold promise for advancements in medical imaging, deep-sea exploration, and other areas......»»
Plasmonic modulators could enable high-capacity space communication
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The.....»»
The ozone hole above Antarctica will keep opening up each spring for decades to come: Why that still matters
At this time of year, as the sun rises over Antarctica, a "hole" opens up in Earth's ozone layer......»»
Feeling the heat as Earth breaks yet another record for hottest summer
Summer 2024 sweltered to Earth's hottest on record, making it even more likely that this year will end up as the warmest humanity has measured, European climate service Copernicus reported Friday......»»
Plant thermogenesis has played key role in attracting pollinating insects for at least 200 million years, study suggests
Thermogenesis is a process by which organisms generate internal heat. Although it is usually associated with animals, some plants have also developed this ability. This metabolic process allows certain parts of the plant, such as flowers and inflores.....»»
Dangerous heat wave intensifies in US Southwest
A punishing heat wave gripping California and parts of the southwestern United States was intensifying Thursday as forecasters warned of dangerous temperatures......»»
Gravitational waves unveil previously unseen properties of neutron stars
A better understanding of the inner workings of neutron stars will lead to a greater knowledge of the dynamics that underpin the workings of the universe and also could help drive future technology, said the University of Illinois Urbana-Champaign ph.....»»
Eclipses create atmospheric gravity waves, student teams confirm
Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured d.....»»
After Starliner, NASA has another big human spaceflight decision to make

NASA mission gets its first snapshot of polar heat emissions
NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experim.....»»
Scientists demonstrate giant THz Kerr effect via stimulated phonon polaritons
Terahertz (THz) waves and THz technologies have gradually opened a new style for communications, cloud-based storage/computing, information contest, and medical tools. With the advancement of THz technologies, studies on THz nonlinear optics have eme.....»»
Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»
Five lessons from ancient civilizations for keeping homes cool in hot, dry climates
Modern buildings tend to take electricity and air conditioning for granted. They often have glass facades and windows that can't be opened. And when the power goes out for days in the middle of a heat wave, as the Houston area experienced in July 202.....»»
New ransomware group is hitting VMware ESXi systems hard
Researchers spot a new ransomware actor called Cicada3301, but it's not linked to the game of the same name......»»
Global South cities lack cooling green spaces
Cities in the Global South are more exposed to extreme heat because they lack cooling green spaces, new research shows. The study found that Global South cities have just 70% of the "cooling capacity" provided by urban greenery in the Global North. T.....»»
Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
By studying data from NASA's Parker Solar Probe and the ESA Solar Orbiter, an international team of astrophysicists has found that Alfvén waves drive the acceleration and heating of the solar wind......»»
Study finds lower-income NYC residents trade comfort for affordability
In a revealing piece of research coauthored by a Singapore Management University academic, public policies to ease urban heat in one of the largest first world cities have seen price gaps emerge between homes in cooler and hotter areas, with lower-in.....»»
Study reveals key strategies to combat urban heat vulnerability
A QUT study analyzing five decades of research and thousands of studies has identified five critical areas needed to tackle urban heat vulnerability (UHV), a growing issue impacting millions in increasingly heat-prone cities......»»
